Windows compatibility?

[Zerrvr]

I have everything installed, but when I run it, it errors out with a "Winpath" issue. is there any way to make this work, or do I need to bite the bullet and learn linux?

[slhck]

Can you please post the entire error?

I don't have a Windows machine to test with but it should be cross platform compatible.

I'm running it through Powershell as admin, if that matters

[slhck]

Something was wrong with the way paths were used here. I released a new version; can you please try this one?

pip3 install --upgrade compress-pptx

[Zerrvr]

So there was progress, we have a new error!

Okay, I believe this might be an issue with convert on your system. Is that the tool from ImageMagick? I suspect it's something else. Can you please run convert -h or similar to find out what that is?

[Zerrvr]

I have the most up to date windows binaries installed, and I made sure to install the "legacy commands"...

PS C:\Users\runne> convert -help Version: ImageMagick 7.1.1-19 Q16-HDRI x64 99da019:20230930 https://imagemagick.org Copyright: (C) 1999 ImageMagick Studio LLC License: https://imagemagick.org/script/license.php Features: Channel-masks(64-bit) Cipher DPC HDRI Modules OpenCL OpenMP(2.0) Delegates (built-in): bzlib cairo flif freetype gslib heic jng jp2 jpeg jxl lcms lqr lzma openexr pangocairo png ps raqm raw rsvg tiff webp xml zip zlib Compiler: Visual Studio 2022 (193532217)...

[Zerrvr]

I'm looking into this: https://legacy.imagemagick.org/Usage/windows/#convert_issue, may be my issue

[slhck]

Please see https://stackoverflow.com/a/9035861/435093.

I released a new version that uses the non-legacy commands, so it should be more portable.

[Zerrvr]

Victory! Works like a charm. Thank you so much for your help, and so fast, too!

[slhck]

Great, I'm glad it worked!
